“block of code…” is the piece of code that operates on the array values.“$array_value “ is the temporary variable that holds the current array item values.“$array_data” is the array variable to be looped through. “foreach(…)” is the foreach php loop block code.Only arrays are supported by the Foreachloop, which is used to loop around each key/value pair in an array. The current array element’s value is allocated to $value in each pass, the array pointer is shifted by one, and the next element is processed in the next pass. To loop through arrays, use the Foreach Loops. At the completion of each iteration, it is evaluated. increment – It adds a new value to the loop counter.If it evaluates to false, the loop is terminated. The loop persists if it evaluates to true, and the nested statements are executed. condition – State is assessed at the start of each iteration.initialization – It’s used to set the counter variables, and it’s checked once unconditionally before the loop’s body is executed.The following are the definitions of the (for loop) parameters: The for loop in PHP is similar to the for loop in Java/C/C++. It helps users to centralise all loop-related comments. When you already know how many times you want to run a block of code, you use for loop. If the number of iterations is specified, it should be used otherwise, a while loop should be used. It’s usually used to repeat a block of code a certain number of times. The For loop is a control structure that repeats a block of code as long as a condition is satisfied. Since the condition is checked at the conclusion of the loop iteration rather than at the beginning, a ( do-while loop) will only be executed once, even though the conditional expression is false. The ( while loop) differs from the do-while loop in one crucial way: for a ( while loop), the condition to be evaluated is checked at the start of each loop iteration, so the loop can never be executed if the conditional expression evaluates to null. Output:- Difference Between While and Do…While Loop A ( do-while loop) executes a block of code once, then evaluates the condition if the condition is true, the expression is repeated as long as the given condition is true. The ( do-while loop) is a while loop variant in which the state is evaluated at the conclusion of each loop iteration.
